My training calendar is currenlty summarized by 4 numbers,
Hours, Miles, Personal Records, Activities
It would be nice add more information that allows users to figure out there average pace running or average speed when biking. It would also be great to see how heart rate evolves over time with pace. I am not entirely sure how to do that, but I'd like to know if my HR is lower at the same pace from one year to the next.
